SHING'LING-BRACIKET.

SPECIFICATION forming part of Letters Patent No. 434,348, dated August12,1890.

Application filed April '7, 1890. Serial No. 346,918. (No model.) I

To all whom it may concern.-

Be it known that we, THOMAS LEVI and JAMES W. MURCHISON, of- NewWestminster, British Columbia, Canada, have invented a certain new anduseful Improvement in Shingling-Brackets, of which the following is aspecification.

This invention is an improved shinglingbracket or bracket for connectionwith a shingle-roof to support a beam or scantling against whichthecarpenter or other workman may rest in shingling or repairing a roof, inbuilding or repairing a chimney, or in doin g any other work on ashingle-roof.

The invention consists in the novel construction of the device, as willbe hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 shows the bracket as in use. Fig. 2 is an edgeview of the bracket. Fig. 3 is a top plan view thereof; and Fig. 4 is adetail perspective view of the bracket, all as will be hereinafterdescribed.

The bracket consists of the main plate A, the stirrup B, the shingle-recess 0, having the bearing-plate D, and the dog E, pivoted at itslower end e, and having spurs or serrations E E, arranged, respectively,at its free and pivoted ends and arranged and adapted to bite into ashingle having its butt-end inserted in the recess 0. It will be noticedthat the dog E is pivoted to the main plate at about the lower end ofsuch plate and alongside the same. It will also be noticed that thebase-plate D extends laterally at (1 past the main plate, so that itwill lie immediately below the dog E and form a jaw or bearing on theopposite side of a shingle clamped by said dog, so that the shingle willnot be split or broken by the dog. At its lower end the extension d isformed with a stop-flange d, which facilitates the setting of thebracket in true position on a roof. The outer arm I) of the stirrup Binclines outward toward its upper end, forming a wedge-like bearing forthe bar or scantling forced down in such stirrup B, and the dog E is soformed that its upper surface 6 projectsinto the stirrup in position tobe pressed upon by the scantling forced therein to cause its spursorserrations to bite into the shingle, and so clamp the bracket inplace.

In applying the bracket the plate D is placed under the butt-end of anyone of the shingles and the end of the main plate A is inserted underthe butt end of the next upper shingle. Now if a piece of scautling beforced down in the stirrup it will cause the dog to clamp the butt-endof the shingle and so hold the bracket firmly in place. It will beunderstood that these brackets are usually used in pairs or sets, abracket being arranged to support each end and the middle of thescantling or foot-board, or be placed eight or ten feet apart.

Having thus described our invention, what we claim as new is- 1. Theimproved bracket consisting of the main plate, having at its lower end astirrup B, and a shingle-recess 0, having a bearingplate D, and the doghaving spurs or serrations and arranged to be clamped against a shingleinsertedin recess 0 by a seantling or foot-bar pressed into the stirrupB, substantially as set forth.

2. The improved bracket consisting of the main plate A, having a stirrupB, and shingle-recess 0, having a base-plate D extended at cl to oneside of the plate A, and the dog hinged or pivoted atone end and movablealongside of plate A above the extension 61 of plate D, allsubstantially as and for the purposes set forth.

3. The improved shingling-bracket having its main plate provided with astirrup and with a plate D, and provided with a dog pivoted at one endand free at its opposite end, and provided at its free and pivoted endswith spurs or serrations, all substantially as and for the purposes setforth.

4. The improved shingling-bracket herein described, consisting of themain plate A, having stirrup B, the outer plate I) of which inclinesoutward toward its upper end, the base-plate D, having alateralextension dbeyond the side of plate A, and provided at the lower edge ofsuch extension cl with flange (l, and the dog E, pivoted at e alongsidethe plate A, and having spurs or serrations E E near its free andpivoted ends, substantially as set forth.
